The Seasonic M12 II Bronze Evo Edition excelled in our tests, achieving some fantastic technical results under demanding situations.

The appearance of the M12 II Evo Edition is immediately reassuring – the quality of finish easily achieves the standard we would expect from Seasonic. The bundled cables are very high grade and with six 6+2 pin PCIE cables included there is plenty of potential for a high specification SLI or Crossfire system build.

The pure modular design will appeal to the demanding enthusiast audience who are building a showcase system complete with backlit window panel. The adoption of flat ‘ribbon' style modular cables ensures that routing will be straightforward.

Technically the unit is exemplary. Load regulation is rock solid and it dealt with our intensive cross loading test without a hitch. Noise suppression is excellent and all rails fall well inside industry tolerance guidelines. Our testing showed that the unit is over specified and we were able to hit around 960W before the unit shut down safely. The use of high grade 105c rated Japanese capacitors is always a plus point, especially if you live in a warm climate.

The Seasonic M12 II Bronze Evo Edition achieved close to 80 Plus Silver certification in our tests, well ahead of the 80 Plus Bronze claims.

The supply isn't the quietest we have tested although under most circumstances it doesn't emit a lot of fan noise. With a 700W+ load demand the fan can be heard, although the pitch of the rotor rotation is low, so it isn't distracting.

Pricing in the United Kingdom hasn't been confirmed but Seasonic told us they expect the unit to be priced below £130 when it ships in the coming weeks. A 750W unit will also be released in this range, but we have no pricing information yet for that model.

Pros:

• Strong ripple suppression.
• deep paint.
• 105c japanese capacitors.
• achieved 80 Plus Silver efficiency in our tests.
• delivered 964 watts before shutting down.
• fully modular.
• flat cables.

Cons:

• Won't be cheap.

Kitguru says: Another stellar power supply from the Seasonic design team.
